- Ignition Source
In fire safety, an ignition source is any heat, spark, flame or chemical reaction that can ignite a material or substance, causing it to catch fire.
Common ignition sources include;
- open flames;
- electrical equipment;
- hot surfaces;
- sparks from welding or grinding;
- static electricity;
- exothermic chemical reactions;
- chemical reactions that involve substances that are highly reactive or unstable.
Spontaneous combustion can be considered a type of ignition source because it generates the heat necessary to ignite materials without any external heat, flame, or spark.
